ABSTRACT:
An optical disk recording and/or reproducing apparatus (100) includes a first case (110), a base (130), and a main body (140). The first case includes a supporting device (116) with a hole (118) defined therein, and a disk clamper (10). The main body is accommodated in the base, and includes a spindle motor (142) and a turntable (148). A magnetic element (149) is positioned on the turntable. The disk clamper includes a clamping body (12), a magnet (14), and a clip (16). The clamping body and the clip are respectively positioned on lower and upper sides of the supporting device, and fixed together through the hole. The magnet is sandwiched between the clamping body and the clip. In use, because of attraction of the magnet and the magnetic element, opposite sides of an optical disk (220) are respectively clamped by the clamping body and the turntable.
